The nuts I5 are mounted on threaded spindles I6 which are supported in the drum wall Il so that they can rotate but are incapable of axial displacement. The lefthand end of each spindle i6 carries a sprocket I8 and a chain I9 is laid over all the sprockets IS. One of the threaded spindles I6 is provided with a handwheel 20. Upon rotation of this handwheel,` the "threaded spindle i6 and sprocket IS associated therewith are rotated, the rotation of the sprocket being transmitted through the chain i9 to all the other sprockets I8 so that same are rotated to exactly the same extent. As can at once be seen, it is thus possible to adjust the inclination of the outwardly projecting arms of the bell-crank levers l2 simultaneously and to the same extent.

What I claim is:

1. Warping mill with a rotatably supported drum, and with a plurality of bell-crank levers adjustable simultaneously and to the same extent, said bell-crank levers being pivotally supported at one end of the drum, the bell-crank lever arms directed towards the axle of the drum being forked, a pin fixed on a nut entering between the two prongs of the fork-shaped lever arm, the whole being such that the nut is adjustable in the direction of the drum axis by means of a coordinated threaded spindle.

2. Warping mill with a rotatably supported drum, and with a plurality of bell-crank levers adjustable simultaneously and to the same extent, said bell-crank levers being pivotally supported at one end of the drum, the bell-crank lever arms directed towards the axle of the drum being forked, a pin fixed on a nut entering between the two prongs of the fork-shaped lever arm, the whole being such that the nut is adjustable in the direction of the drum axis by means of a coordinated threaded spindle, each threaded spindle carrying a sprocket at one end and a chain laid over all these sprockets.

3. Warping mill with a rotatably supported drum, and with a plurality of bell-crank levers adjustable simultaneously and to the same extent, said bell-crank levers being pivotally supported at one end of the drum, the bell-crank lever arms directed towards the axle of the drum being forked, a pin fixed on a nut entering between the two prongs of the fork-shaped lever arm, the whole being such that the nut is adjustable in the direction of the drum axis by means of a coordinated threaded spindle, each threaded spindle carrying a sprocket at one end and a chain laid over all these sprockets, one of the threaded spindles being provided with a handwheel.

4. Warping mill with a rotatably supported drum, and with a plurality of bell-crank levers adjustable simultaneously and to the same extent, said bell-crank levers being pivotally supported at one end of the drum, the bell-crank lever arms directed towards the axle of the drum beingforked, a pin xedon a nut entering betweenthe two prongs of the fork-shaped lever arm, the whole being such that the nut is adjustable in the direction parallel to the drum axis by means of a coordinated threaded spindle, each threaded spindle carrying a sprocket at one end and a chain laid over all these sprockets, one of the threaded spindles being provided with a handwheel, the threaded spindles being supported in the drum so that they can rotate but not be displaced axially.

5. Warping mill of the sectional type comprising in combination a rotatably supported drum provided with a plurality of bell crank levers adjustable simultaneously and to the same extent. said bell crank levers being pivotally supported at one end of said drum, a pair of coaxial bearings, an axle rotatably mounted within said bearings and axially displaceable therein, said drum being iixedly mounted on said axle, means for axially displacing said axle upon rotation thereof and for axially displacing said axle in the reverse direction without rotation, said means comprising a drive shaft arranged parallel to said axle, a pinion secured to said shaft, a gear secured to said axle meshing with said pinion, a bushing having an internal thread rigidly secured to one end of said axle, a threaded spindle engaged with the thread in said bushing, a worm gear secured to the outer end of said spindle, and a worm meshing with said worm gear for rotating same independently of said drive shaft.
